BBA is from lack of co2 - increase the amount of co2 you add to the tank (and supplement excel is good too), aside from that, looks great!

Hey Frank,

I'll keep an eye on the CO2. Maybe it is the culprit. I've got pretty excellent diffusion happening in the tank right now. however, I may be completely wrong. this is the first time I've seen this algae in this tank. Part of me is also thinking it's time to change the light bulb. co2 and light and the plant detritus could all be the culprit. thanks for the info. My drop checker solution may need to be renewed. I'm gonna take a look at it manana. much love. -el g
